.T0 all whom it may concern.'

Be it known that I, JOHN N. VALLIS, of the town of Fleming, in thecounty of Cayuga, in the State of New York, have made a new and usefulImprovement in Hand Shears or Ni ppers, and I do hereby declare that thefollowing is a full, clear, and exact description thereof, referencebeing had to the aecompanying drawings, and to the letters of referencemarked thereon.

The object of this invention consists in the peculiar arrangement ot'the several parts, to the end that less power or force shall be requiredto operate the saine than in any here tofore in use.

Figure lis a plan of said shears. Fig. 2 is an edge view. Fig. 3 showsthe opposite side from that shown in Fig. l.

In Fig. l, A is one ofthe front levers. B is the other. O and D are thetwo rear levers. To the levers A and B are secured pieces of steel, Eand F, which forin the cutting edges. The opposite ends ot' said leversare curved inward. 'lhe curved pieces G on the lever A, and the piece Hof like form on the rear end ofthe lever B, have slots I and J in each,and said pieces are secured to each of the said levers by means ofscrews. rlhe levers G and D are jointed to the levers A and B at K andL. The curved pieces G and H have a slot in the rear end of each, intowhich the studs M and N are secured. Said studs as the5T pass throughthe slots ,enter into and secure the curved pieces H aud G to the leverC and D. Underneath each of said curved pieces G- and H are pulleys Oand I), having their eenters at Q. and It. The slotsin the rear end ofthe plates G and H serve to hold the pulleys O and I) close againstthetwo inclined planes S and T on the inside of the levers C and D.

And now it will be observed that whenever the rear end of the levers Cand D are pulled apart the cutting-edges will be opened, and when madeto approach each other the euttin ged ges will approach.

Having described the inode of constructing and opera'ing my invention,what I wish to secure by Letters Patent is- The friction pulleys O andP, working against thelevers G and D, in combination with the slots Iand J, or their equivalents, as set forth.
